END -DUMP GAR.

Specification of Letters Patent.

Patented Dec. *7, 1915.

Application filed April 20, 1914. Serial No. 833,127.

To all whom it may concern:

Be it known that I, ORLANDO F. HART, a citizen of the United States of America, residing at Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in End- Dump Cars, of which the following is a specification.

lily invention. relates to improvements in railway cars in which materials are carried whichit is desirable to unload quickly and at specified places; and particularly the cars used in grading for railroads, for hauling ores, gravel, sand, coal and the like.

The objects of my invention are, first to provide a car whose load can be dumped out at its end or ends; and, second, to provide practicable means for easily, quickly and inexpensively doing so.

With those and other objects in view my invention consists in the novel details of construction and combination of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Similar characters refer to like parts throughout the several views in which Figure 1 is a perspective view of the body of such a car equipped withmy improvements, and broken away as to its'near side. Fig. 2 is a front'elevation showing a car after having been unloaded and with the near side of the car omitted. 'Fig. 3 is another view, in elevation, of a car equipped with my improvements; and Fig. 41 shows an elevation of a detail and a section of the same. r I

A convenient illustration for the use and operation of my improvements is obtained by describing it as used in grading for the purpose of laying ties to support the rails of a new railway. The track having been laid as far as the terminal 1, and it being necessary to fill in therebeyond at the spot 2, a car 3, shown empty, after having been loaded with grading material, is pushed by an engine up to a suitable point near the end of the constructed track and its brakes not shown) are'locked to retain it at that location during the operation of unloading it. The load lies on a false bottom or plate 4:, provided with a turned up wall 5 at one end to prevent portions of the load spilling over that end and falling on to the bottom, proper, of the car. A chain 6 is attached to the plate 1 at its 5 end near the wall 5, (or it may be attached to the top of the latter) and a hook 7 near the top of the end 8 of the car or at any convenient point on it is provided, on which one hangs the chain 6 while not inuse to avoid its getting buried under the load. The other end, 9, of the car is made as a separate piece rotatively hinged or pivoted,as illustrated, as to its sides near its top, to the side walls 10 and 10, of the car, with pivots 11, 11. The end 9 is made high enough to project above the sides 10, 10 with a pair of ears 12, 12, extending upward from its middle for a purpose that will presently be described, or a single ear can be used, or the end 9 can be made of the same height as the sides of the car and the end 8, and a longer projection similar to the pair of cleats 13, shown attached to the end 8 and which support between them a horizontal spool or roller 14:, can be used instead. A ring 15, or its equivalent, is attached to'the bottom of the end 9. A chain 16 (or its equivalent) is attached at one end, 17, to the operating locomotive engine (not shown); is passed over the roller 14 and between the ears 12, 12, with a cross bar 18 through one of its links at the rear of the cars 12, 12, (or a link may be looped on a single car when so provided, or the links may be wide enough so that a horizontal link will catch behind the ears 12, 12 while its companion link stands vertically between them); The chain 16 is then passed on down and is'hooked to the ring 15, inpractice, after the car has been loaded: the bottom of the end 9, being U latched or held in locked relation to the bottom, 3, of the'car by any conveniently operable device. The engine having pushed the car to the right location and the cars brakes having been set; the end 9 is unlocked andthe engine backs away from the car, drawing the end 17, and the chain 16 with it. 'The chain 16 first draws on the ears 12, 12, and the part of the end 9 above the pivots 11, 11 canting the end 9 partly open until the bar 18 slips off over the ears 12, 12, whereupon the chain 16 pulls on the ring 15 and turns the end 9 over until it occupies the position shown in Fig. 2, where it rests supported by pegs 19, 19, one on either side of the car and projecting therethrough.

On the outer sides of the car pivoted hooks 20, 20 are fitted so that when the pegs 19, 19 are driven out the hooks will fall into the annular grooves 21, 21, and when the pegs are driven in under the end 9, (Fig. the hooks will fall into the grooves 22, 22, thus locking the pegs l9, l9 temporarily where needed. The end 9 having been fully opened and turned over, the chain 16 is unhooked from the ring 15 and is hooked to the upper end of chain 6, which has been released from the hook 7, The engine continues to back away and draws the chain 6, also, over the roller 14 thereby elevating the end 5 of the plate 4 so that the load on it slides off its other end, out of the open car end and on to the ground at the spot 2. The engine is then brought up to the ear again. The chains 16 and 6 being then slack, the load ingoing out ordinarily carries the plate 4: with it onto the ground; though sometimes its ejectment is assisted by the unloaders. Pegs 19 may be used in the sides of; the car to help chain 16 support the bottom 4. To facilitate the movements of the plate 4, a roller, usually in the form ofa round iron bar 23, is left under the plate 4:

at its end adjacent to the car end 9. The roller bar 23 goes out into the ground with the plate 4. in Fig. 3 the roller 23 is shown just before it will have dropped to the ground when the space between the ear and the plate 4 has exceeded its diameter. Run-' ning the plate 4 out of the car enables the unloaders to easily scrape out any material that may have fallen onto the car bottom 3.

r The engine then backs away enough to draw the plate 4 up so that its end 5 rests on the car bottom 3. The car end 9 is then turned over again so that its lower end rests on the plate 4, as shown in Fig. 3. The engine backs more and draws the plate 4 back to its original position shown in Fig. 1, whereupon chain 6 is unhooked and again hung up on hook 7. Drawing the plate 4 inward from the position shown in Fig. 3 causes the bottom of the car end 9 to sufficiently clean it. To prevent the end 9 from pinching onto and looking the plate 4, the bar 23 is pickedup from the ground and temporarily pushed between end 9 and plate 4 as shown It will be apparent to those familiar with dump cars and their operation that I have invented improvements,which though rough and heavy as the necessities of the work require, are practical, economical and enduring- I' claim:

1. A car having an end pivoted at the top and free at the bottom and means for opening said end, in combination with a false bottom for said car and means for elevating the end of said bottom opposite said car end, for the purpose set forth and as shown and described.

2. A car having a false bottom, suppor ing its load, connected at one end with a lifting device; a revoluble end pivoted near itstop to, the sides of said car and attachable at its lower end to traction mechanism, as described and for the purpose set forth.

3. The combination of a dump car having one end pivotally mounted near its top and extending above the sides thereof, and a false bottom; with flexible traction mecha nism passing over said top and attachable at the bottom of said end and flexible traction mechanism attached to one end of said false bottom, for the purpose set forth.

4. An end-dump car comprising a car body with a pivoted end, an extension of said end above the sides of the car; an elevated guide and bar extending above the other end of said car; a chain attachable to the lower end of said pivoted end and passing over said extensions; a false bottom to said car, and chain attached to said bottom at one end thereof, for the purpose set forth.

5. An end-dump ear comprising a car body with a false bottom turned up at one end, and connected with a lifting chain at said end; a-roller; a rotatable end pivoted near its top to the sides of said car; adjust able pegs through. said sides near their tops and a chain attached to said pivoted end and conneetible with a traction operating mechanism. I

In testimony whereof I affix my signature in presence of two witnesses.
